在这些图中,贯穿附图的多幅图形,附图标记引用本发明的同样的或等同的部分。
具体实施方式
下面将对本发明的各个实施方案详细地作出引用,这些实施方案的实例被显示在附图中并描述如下。尽管本发明将与示例性实施方案相结合进行描述,但是应当意识到,本说明书并非旨在将本发明限制为那些示例性实施方案。相反,本发明旨在不但覆盖这些示例性实施方案,而且覆盖可以被包括在由所附权利要求所限定的本发明的精神和范围之内的各种选择形式、修改形式、等价形式及其它实施方案。
图1至图4涉及根据本发明示例性实施方案的混合动力***的动力结构,其中图1为显示根据本发明示例性实施方案的混合动力***的动力结构的构造图,且图2至图4为显示根据本发明示例性实施方案的混合动力***的动力结构的动力流的构造图。
将参考附图对本发明的示例性实施方案进行详细描述。
如图1至4所示,根据本发明示例性实施方案的混合动力***的动力结构包括与行星齿轮部件180的太阳轮101连接的第一马达110、与内齿圈102连接的第二马达120,和与行星架103连接的发动机131和制动器132,以改进混合动力车的行驶性能。
在下文中,根据本发明的示例性实施方案的混合动力***的动力结构的每个组件将参照附图描述。
首先,本发明的示例性实施方案包括行星齿轮部件180。行星齿轮部件180的太阳轮101、内齿圈102和行星架103与第一马达110、第二马达120、发动机131和制动器132连接,且与内齿圈102连接的第二马达120与驱动器150连接以输出动力。
如图1所示,行星齿轮部件180构造为包括太阳轮101、行星架103和内齿圈102。
第一马达110与太阳轮101连接,而不是与行星齿轮部件180(该行星齿轮部件180包括太阳轮101、行星架103和内齿圈102)中的输出部件和输入部件连接。
第二马达120与作为输出部件的内齿圈102连接,并与如下所述的驱动器150连接。
在该构造中,安装于混合动力车中的第一马达110和第二马达120控制发动机最佳工作点,其是所述混合动力***的最大优点。本发明的示例性实施方案可包括两个马达来控制工作点,由此改进行驶性能。
作为输入部件的行星架103与产生车身动力的发动机131连接,以接收发动机131的动力。
此外,行星架103也与制动器132连接,并控制与太阳轮101连接的第一马达110和与内齿圈102连接的第二马达120的驱动。
同时,第一马达110和第二马达120可与电池140连接,以操作第一马达110和第二马达120。
此外,与内齿圈102(该内齿圈102作为输出部件)相连接的第二马达120与连接车辆车轮的驱动器150连接,以通过内齿圈102将动力输出传递至驱动器150,由此驱动车辆。
在下文中,在根据本发明的示例性实施方案的混合动力***的动力结构中,将在以下描述每个模式转换。
图2为显示在EV模式下在启动发动机之时的动力流的视图。混合动力车以EV模式行驶,所述EV模式在启动初始车辆之时直接传输马达的动力。在此情况中,第一马达110在未加载下以如下状态旋转:在EV模式过程中发动机131停止工作而不产生动力。同时,当在EV模式的行驶过程中发动机以混合电动车辆(HEV)模式开始被驱动时,第一马达110转换为发电机以将发动机131增加至发动机启动容许速度,然后启动发动机131。
图3为显示在将EV模式转换为HEV模式之时的动力流的视图。当在发动机131启动之后进入HEV模式时,第一马达110和第二马达120各自用作发电机和马达,从而进行控制以驱动E-CVT,即在最佳工作点下的发动机工作点。同时,第二马达120与输出部件直接连接,并因此主要用作马达来辅助动力。
图4为显示在将EV模式转换为另一EV模式时的动力流的视图。当在EV模式中仅有第二马达120被驱动时,由于分级情况或增大的车辆速度使得第二马达120的速度过大,这导致在扭矩不足的情况下操作制动器132,从而在另一EV模式下进行驱动。同时,第一马达110和第二马达120均可用作动力源。在本文中,当进行向相反模式的转换时,通过将分散至第一马达110和第二马达120中的转矩集中至第二马达120,并随后释放制动器132,从而进行控制以使得在模式转换之时所导致的影响达到最小。
如上所述,本发明的示例性实施方案可通过使用第一马达110、第二马达120和制动器132来驱动EV***,以改进行驶性能并增加EV容许车辆速度,由此改进燃料效率。
如上所述构造的本发明的示例性实施方案的混合动力***的动力结构被构造为包括:行星齿轮部件、第一马达、第二马达、发动机和制动器,所述行星齿轮部件包括太阳轮、行星架和内齿圈,所述第一马达与所述太阳轮连接,所述第二马达与所述内齿圈连接,所述发动机和制动器与所述行星架连接,从而在EV行驶之时通过两个马达驱动混合动力车,由此改进行驶性能,并增加EV区域而不增加马达尺寸,由此改进燃料效率。
如上所述,本发明的示例性实施方案可在EV行驶之时通过两个马达驱动混合动力车以改进行驶性能,并可增加EV区域而不增加马达尺寸以改进燃料效率。
前面对本发明具体示例性实施方案所呈现的描述是出于说明和描述的目的。前面的描述并不想要成为毫无遗漏的,也不是想要把本发明限制为所公开的精确形式,显然,根据上述教导很多改变和变化都是可能的。选择示例性实施方案并进行描述是为了解释本发明的特定原理及其实际应用,从而使得本领域的其它技术人员能够实现并利用本发明的各种示例性实施方案及其不同选择形式和修改形式。本发明的范围意在由所附权利要求书及其等价形式所限定。
